IPC: G01R31/327
Filed: 1993-08-27
Abstract: PURPOSE:To improve workability by grounding a gas insulation switching device, setting the insulation strength of the secondary side of the transformer of a first power supply part at the specified value or more, connecting one end of the secondary side of the transformer of a second power supply part to one end of a secondary-side loop, and grounding the other end. CONSTITUTION:A gas insulation switching device 30 is set at the grounding potential. As a transformer 12 of a first power supply part 10, which supplies a loop current and a recovery voltage, the transformer, wherein the insulating strength on the secondary side is V0/sq. rt. 3 (V0 is the rated voltage) or more with respect to the primary side, is used. The conducting loop circuit on the secondary side is not grounded. On end a secondary winging 22b of a transformer 22 of a second power supply part 20 is connected to one end of the loop so as to apply simulated grounding voltage V0/sq. rt. 3. The other end of the winding 22b is grounded. In this way, it is not necessary to apply the simulated ground voltage on a tank 31 of the device 30. It is not necessary to provide high insulation in the device 30, and the workability is improved.

Title: Electron beam exposure system and method therefor, and manufacture of devices
Inventor: MURAKI MASATO
IPC: H01J37/304
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To suppress throughput deterioration due to correction of variations in the position of electron beam with respect to stage. SOLUTION: The position of a first reference mark disposed on a stage with respect to electron beams is detected by an electro-optical system for detecting the position of an object to be irradiated with electron beams. The position of the stage relative to the electron beams is obtained by detecting the position of the stage by a length measuring system. The position of a second reference mark disposed on the electro-optical system is detected beforehand by the electro-optical system. On the basis of the obtained relation of position between the electron beams and the stage, patterns are drawn on a substrate with electron beams by using the stage, a means for deflection, and a length measuring system.  At this time, the position of the second reference mark is detected again by the electro-optical system, and the difference between the position of the second reference mark and that of the mark previously detected is determined. Based on the difference, the relative position between the electron beams and the stage is corrected by at least either of the means for deflection and the stage.

Title: Switching circuit
Inventor: TAKESHITA MASAHIRO
IPC: H03K17/60
Filed: 1981-12-28
Abstract: PURPOSE:To suppress the output voltage less than the breakdown strength of a switching circuit, by connecting a diode between a power supply and the output of a switching circuit which projects a character signal and a TV image superposed on each other and at the same time connecting a constant voltage diode between input terminals of another circuit. CONSTITUTION:A control is performed to lower the video contrast when a character signal and a TV image are superposed on each other to be projected with reproduction on a cathode-ray tube. In this case, the cathode of a constant voltage diode 10 of 8V connected between a transistor 8 and an output terminal 4 for control of contrast is set at 10V with the anode at the side of a terminal 3 of an integration circuit 1 set at 5.7V respectively when the terminal 3 of the circuit 1 which processes the received character signal is receiving a video signal and while the transistor 8 is cut off. Therefore the diode 10 does not conduct, and the terminal 3 does not exceed the breakdown strength of the circuit 1 since it is set at 5.7V. When the transistor 8 coducts and an image is superposed on characters for projection, the diode 10 conducts. At the same time, the voltage of the terminal 4 is dropped down to 8V to lower the contrast.

Abstract: PURPOSE:To secure a hydraulic unit and an antiskid braking system compact in size and lighter in weight as well as to provide such a jig as optimum for assembling a solenoid valve to a storage case. CONSTITUTION:A member in an inner circumferential part of a storage hole part 28 of a storage case 3 is fluidified by plastic deformation and stuck close to two grooves 51, 52 of each outer circumferential part of two solenoid valves 1 and 2 just as plastic bonding, thus they are joined together in a state that a residual stress at the time of being plastically deformed is left behind. In consequence, the solenoid valves 1, 2 and the storage case 3 are firmly secured to each other after being sealed up. Therefore, strength in a cover 4 becomes disused, whereby all bolts for cover locking use can be miniaturized and reduced, thus miniaturization and lightweightiness for a hydraulic unit and an antiskid braking system are well promoted so far as a portion for that. Moreover, owing to a jig 7 consisting of a temporary clamping part 8 and a pressing part 9, assembling of these solenoid valves 1, 2 to the storage case 3 for those of hydraulic unit and antiskid braking system becomes facilitated.

Filed: 1994-09-08
Abstract: PURPOSE: To obtain a thermal head having excellent life characteristics by providing the step of generating an electromagnetic induction current at a heat generating resistor by forming an electrode layer on the resistor formed on a support base. CONSTITUTION: In a method for manufacturing a thermal head, the step of generating an electromagnetic induction current at a heat generating resistor is provided before the step of forming an electrode layer on the resistor. The step of generating the current is after the step of forming the layer, and when the layer is formed when the current is generated at the resistor, the current flows to the electrode side to heat it. The mutual diffusion of the heated layer and the resistor occurs. Accordingly, the step of generating the current at the resistor is placed before the step of forming the layer on the resistor, and hence the resistor can be selectively annealed, and the head having excellent life characteristics can be realized.
